JaCVAM statement on theShort Time Exposure In Vitro Test Method for assessing ocular irritation
At a meeting held on 3 March 2016 at the National Institute of Health Sciences (NIHS) in
Tokyo, Japan, the Japanese Center for the Validation of Alternative Methods (JaCVAM)
Regulatory Acceptance Board unanimously endorsed the following statement:
Proposal: The Short Time Exposure (STE) In Vitro Test Method is a suitable means forassessing ocular irritation potency in a regulatory context as part of either a topdown approach to screening test chemicals that potentially induce serious eye
damage (Category 1) or a bottom-up approach to screening test chemicals that
potentially induce neither eye irritation nor serious eye damage and therefore do
not require classification (No Category) under the United Nations GloballyHarmonized System of Classification and Labeling of Chemicals (GHS).
This statement was prepared following a review of a validation report prepared by theJapanese Society for Alternatives to Animal Experiments (JSAAE) and JaCVAM, a peer
review report prepared by the Interagency Coordinating Committee on the Validation ofAlternative Methods (ICCVAM) and the National Toxicology Program (NTP) Interagency
Center for the Evaluation of Alternative Toxicological Methods (NICEATM), andOrganisation for Economic Co-operation and Development (OECD) Test Guideline (TG)491 “Short Time Exposure In Vitro Test Method for Identifying i) Chemicals Inducing
Serious Eye Damage and ii) Chemicals Not Requiring Classification for Eye Irritation orSerious Eye Damage,” as well as other materials prepared by the Ocular Irritation Testing
JaCVAM Editorial Committee to acknowledge that the results of a review and study by theJaCVAM Regulatory Acceptance Board have confirmed the usefulness of this assay.
Based on the above, we propose the Short Time Exposure In Vitro Test Method as a usefulmeans for assessing ocular irritation potency during safety assessments by regulatoryagencies.
